"Non-Q wave," alias "nontransmural," myocardial infarction: a specific entity.

abstract：OBJECTIVE:Racial differences in cardiovascular mortality among women remain largely unexplained. Preliminary data suggest that African American and Caucasian differences in endothelial function may parallel differential cardiovascular disease (CVD) risk in women. To further study differences in endothelial function bet...
